Qld/NSW Summer rainfall/slopes and plains

 

Where is the summer rainfall/slopes and plains region?

This region covers the slopes and plains of northern NSW and southern Queensland that have summer-dominant rainfall, averaging 400 to 650 mm per year. Summers are hot and winters are moderately cold with more frosts in the eastern parts.

The southern and northern boundaries are lines running east-west through Warren, New South Wales and through Roma, Queensland, respectively. The eastern boundary runs north from Gilgandra (NSW) to Siding Springs just west of Coonabarabran, then through Narrabri, Yetman and Texas, then south of Warwick, and then along the range north to Kingaroy (Qld). The western border goes from Mitchell (Qld) in the north, to Bollon, Goodooga, and Brewarrina, ending between Nyngan and Cobar (NSW) in the south.

Other towns in this zone are Walgett, Coonamble, Wee Waa, Moree, Mungindi, Dirranbandi, St George, Goondiwindi, Inglewood, Moonee, Surat, Millmerran, Chinchilla, Dalby and Toowoomba.

This region corresponds to the WestWorm (NSW DPI) and Wormbuster 1 (except Stanthorpe), 2a and 2b (Qld DAFF) zones.

These boundaries are approximations only as seasonal conditions vary.

A map of the region is shown below.
